From the Stitch Description: Both versions of this pattern are very dense, and must be worked on large needles lest the stitches become too tight. Fabric Stitch produces a fabric that is firm, close, flat, and sturdy, therefore ideal for sports wear and “hard use” articles like cushion covers and slippers. Worked on large needles in heavy cotton yarn, and surrounded by a fringed edging, either version makes delightful place mats. Double Fabric Stitch, because of its thickness and body, is good for hot-dish mats and potholders.
